Application filed September 18. E929.

To allwtom t 'may` concern.:

Be it known that li, (li-manne V. PATERNO, a citizen of the YUnited States, and resident of the city of New York, in the county of New York and State of New York, have invented certain` new and useful improvements in Boiler Constructions, of which the following is a specification.

This invention relates to a means for preventing corrosion of boilers, hot water tanks, service heaters or the like, the object being to provide a simple and inexpensive device, in the form of a removablelining, capable of ready application to any boiler or hot water heater to protect it from the corrosive elements, such as dissolved oxygen, etc., in the water.

F or a. further comprehension of the in vention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

Fig. l of the drawings is a longitudinal elevation, partly in section, of a heater tank of conventional form, showing one arrangement or embodiment of the invention.

Fig. 2 is a transverse sectional view, show ing a modified form of the removable lining.

Fig. 3 is a detail perspective view showing the arrangement of the removable lining strips employed in the modification shown in Fig. 2.

As here shown, the invention is applied to a supliilementary or service heater tank l, which may be cylindrical in shape, the ends of the tank being numbered 2 and 8, respec tively, and one end, suoli as 3, being a re movable head or cap. The tank is usually a part of the hot water heating system and pipes il and 5 connect opposite ends thereof with the circulation system. I have not considered it necessary to illustrate the device as connected to a boiler or hot water system,

as the particular type or construction there--y of is not material to this invention.

Within the tank l are positioned a series of removable elements, preferably constructed of iron, forming a lining for the same and which by contact with the active or oirculating water passing through the tank remove the gases or corrosive constituents from the water and protect the tank itself Serial No. 411,182.

from other than a negligible corrosive action. r

ln the ar raiigeinent shown in Fig. l, these removable elements comprise a number of tapering rings, such as shown at 6, 7, and 8, which are arranged in series extending collectively from end to end of the tank, the small ends of the several rings nesting within the large ends of the adjacent ones, these rings being of a diameter to lit slidably within the tank and forni a removable lining. The end members 3 and 2 lare also lined with corrugated disks or plates, 9 and l0, respectively, it being understood that these plates and also the rings are loosely held in the tank so as to be easily remo-ved when the end member 3 is taken off. The inlet and outlet conduits 4 and 5 extend through the lining rings so that the active or circulating water is caused topass through the inside thereof. The water be tween the wallsof the tank and the lining soon becomes deactivated by contact withthe metal and remains inactive as to corrosive action on the walls of the tank.

ln the modified form of the invention shown in Figs. 2 and 3, the tank is lined with a series of longitudinally extending strips 12, which strips are relatively thin and arranged `in radial planes, that is, edgewise to the tank wall. These strips `are removable and may be suitably mounted on rods or wires, 13, 14;, 15, which hold them in position at the proper spacing. These strips 12 may extend the full'length of the tank or a number of units may be used and inserted end toy end in the tank.

ln either modification of the invention shown, the water passing through the tank will have its corro-sive constituents removed or deactivated by contact with the removable elements formingthe lining, which elements may be removed and renewal from time to time as they cori-ode, thus protectn ing the tank itself from corrosion.

It will be apparent that the device is simple and inexpensive and may be arranged to be applied to any tank, boiler or hot water service heater.

It will be understood that while I have described the removable elements, such as 7 and 8, comprising the lining, as being of a material which is easily corroded, such as iron, I do not intend to limit the invention wall ot the tank troni the corrosive action of the active or flowing Water. The prineiple is the saine in either case and the onrpose oi the invention is to provide a sin'iple protective lining ivhieh pockets or holds a 'portion ot the Water between the lining and the wall oit the tank, Wliiea Water soon `loecoines deactivated by Contact with the Wall and, in Sonie ases, the lining, and thus will not have a further eorrosive aetion on the wall, the active' water being caused to tloiv inside oi the lininj" and prevented troni coining into contact with the wall ot the tank.

lilhat I claim is: l

i. A device oi the class described, adapted for use with a tank, comprising a removable lining therefor adapted to react with the water passing through said tank to remove the corrosive constituents vtroni said water,

said lining being` inade np oi a series of' tapering rings nested partially one within the other.

2. A device ot' the class described, adapted for use With a tank, comprising a removable lining constructed in part ot' a series of tapering rings nested partiallyv one Within the other and extending rcollectively troni end to end ot the tank and in part of eorrngated plat-es extending across the ends ot said tank, and inlet and outlet condnits for said tank extending through said lining.

3. A device et the class described adapted for nse with a tank, comprising a removable lining oit' readily corrosive material` substantially parallel to and in engagement with the inner Wall ot said tank, and inlet and .outlet conduits extending into said tank through said lining, said lining being iforined of a 1pliiralit)7 of removable sections.
